Abstract
An apparatus in which a six bar linkage cleaner brush retraction/engagement mechanism enables brush retraction (and engagement with the photoreceptor) while providing good control over the brush interference and the capability of changing all of the timing parameters through clutch actuation times in software and clutch shaft speed. The mechanism allows the brushes to retract and engage the photoreceptor independently of one another with relatively soft contacts to the photoreceptor to minimize impacts to photoreceptor motion quality. A four position clutch is used to provide magnetic pole sensor outputs to the system controller to decide when the clutch, which drives the six bar linkage, is engaged and disengaged. The index wheel of the clutch has four equally spaced magnets that are located relative to the retraction crank shaft so that there is a significant amount of time between detecting a pole and the corresponding desired state. An encoder is used to monitor the mechanical drift of each cleaner state.
